OK, in point of fact, this cool gadget from Matt Bitz of Liquidware could be used for pretty much any type of marksmanship training, but “sniper” was a pretty hard headline to resist. It couples Liquidware’s TouchShield Slide, an Arduino Duemilanove, and a lithium battery-pack in a camouflaged aluminum case for a handy range-gadget that records hits on a target—just tap the touchscreen with the tip of a round to mark a hit—and calculates accuracy and precision in real time.
